DUME CAR.

Application filed April 3, 1925. Serial No. 20,419.

The present invention relates to dump bodies for railway cars, motor trucks, and the like, and appertains more especially to that type of dump body wherein a door or side wall at one side is hingedly connected to the bottom or at one edge of the bottom to swing outwardly and downwardly substantially flush with the bottom when the body is tilted toward the correspondin@ side.

It is the object oi the invention to provide extremely simple and inexpensive means for supporting the door or side wall when opened by the tilting movement oi the body and for closing the door or wall when the body is restored to normal or horizontal position, in order that the door operating means will consist of a minimum number ot parts, to reduce the cost of installation and upkeep, as well as providing other advantages.

Another object is the provision of such a device comprising a simple connection between the door or side wall of the body, and support on which the body is mounted, for

`" automatically operating the door or side wall when the body is swung to dumping and normal positions.

lVith the foregoing and other objects in view, which will be apparent as the description proceeds, the invention resides in the construction and arrangement ot parts, as are hereinafter described and claimed, it being understood that changes can be made within the scope ot what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawings, wherein- Figure 1 is an end view of a dump body showing the improvements applied, with the body in normal position.

Fig. 2 is an end view showing the body tilted to dumping position.

Fig. 3 is a plan view of the body in normal position, portions being broken away.

Fig. l is a detail view illustrating` a modiication.

Fig. 5 is an end view of a dump body showing another modilication, the body being shown in normal position in full lines and in dumping position in dotted lines.

Figs. 6 and 7 are end views corresponding with Fig. 5 and showing other modifications.

Fig. 8 is a diagrammatical view showing the improvements incorporated in a two-\vay dump .iody.

Referring particularly to Figs. 1, 2 and 3, the body 1l may be ot' any suitable size and may be the body of a railway car, wagon, motor truck, or the like. The bottom ofthe body is hinged, as at 15, on a support, which, as shown, includes longitudinal sills 16 on a base or plate 17 although any other suitable support may be used. One side wall 18 of the body provides a door which is hinged, as at 19, to tl e corresponding edge ot the bottom of the body, so that said door or side wall may swing downwardly and outwardly to a position substantially flush with the bottom tor the discharge oli' the material in the body i over the door or side wall 18. The hinge 15 is located nearer the side of the body which has the door 18 than the opposite side, in order that when the body is tilted toward that side where the door 18 is located, the

body will swing back to normal or horizontal position under its own weight.

The door operating means consists ot' a cable or other suitable ilexible element 2O at each end of the body having its upper end secured, as at 21, to one end of the door 18 and having its lower end secured, as at 22, to the body support, such as the end ott the sill 16 to which the body is hinged. Nails, Screws or other securing elements may be used for fastening the ends of each cable or flexible element 20 with the door and body support, in order that the cables may be conveniently and quickly fastened in place.

Each cable 20 extends through an aperture in an arm 23 secured to the projecting end portion of the door 18 beyond the end of the body and projecting inwardly or toward the opposite side of the body above the hinge 19. As shown, the arm 23 constitutes part of an angle piece or member 2l secured to the inner side of the projecting end portion of the do-or 18. The points at which the ends of the cables or flexible elements are secured to the door and body support may be quickly determined, without requiring accurate plotting in building'or rebuilding a car, or in making readjustments due to wear and tear. This provides for simplicity and cheapness in cost, both in installation and maintenance.

The arm 23 is of such length,` and the Vpoint of attachment 22 is so located, that when the body is tilted to dumping position, as seen in Fig. 2, the flexible elements 20 are disposed above the axis of the hinge 19, whereby said flexible elements will support Vinwardly to closed position, as seen in Fig.

1. rllhe door 18 has a compound inoreinent,

inasmuch as it swings with the body, and

also swings relatively to the body, and in all positions ot thedoor thel'lexible elements 2l) are under teusilestrain tor supporting the 'door or holding it against the body. lt is thus `possible to use cables, wire ropes or other Vflexible elements tor the connections between the door and body support, inasniuch as said connections are always under tensile strain and are not subjected to com-- pression strains. The flexible elements 2O also bend where they pass through the arms as apparent'by reference to Figs. 1 and 2 showing the two extreme positions. However, the distance between the, point ol"r attaclnneht 22and aperture ot the arin through whicheach element 2O passes remains thesame so that the element 20 does not slide through the arm 23,' thereby avoid ing a rubbing or chaling action, so that the element' 2O will not wear out quickly.

lt will be noted thatv when the body is moved to dumping position, the hinge 19 movesdownwardly closer toward the points of 'attachment 22,' hereby slackening the elements 2O so that the door 1S may swing open, whereas when the body is returned to normal position, the hinge 19 is moved upwardly further away from the points 22 then when the body is in dumping position, so that the elements 2O pull the door to closed position the rbody is swung 'from dumping to normal position. The points 22 of attachment ot the elements 2O are theretore locatedl'ielow the hinge 15 between the body and body support, while the connection ot the element-s 2O with the door 18 must be such that the elements 2O will pull on the door 18 in all positions'ot the body.

Fig. 4 illustrates a modiiication wherein theI arm 23 has a pair of rollers 25 between which the cable ortlexible element 20 passes, thereby reducing friction.

Fig. 5 illustrates the hinge 15 ot the body 1l spaced a different distance from the door 18, and an arm or bar 26 is secured to and projects from the base or plate 17 of the body support for the connection, as at 22a, of the flexible element 20a.

Fig. G shows the `use oli bars 20"`and 2OC in lieu ot thev llexible element, the opposite ends ot said bars being pivotally fastened, as at 21b and 22h, to the door 18 and body support, respectively, in the same manner that the flexible element 20 is fastened as shown in Figs. 1 and 2. The adjacent ends of the bars 20" and 20C are pivotally connected together and to the arm 23", as at 25h. These bars 2()b and 2()C will act the saine as the flexible element 2O ot Figs. 1 and 2, said bars pivoting at the arm 23b and being under tensile strain the saine as the flexible element 20.

Fig. T shows the use ot a rod or link 2Od having its upper end pivotally engaged in an arni 23d secured to the door 1S, and having its lower end piyotally engaged through an aperture in a plate 22d`secured lo the corresponding eud oi the body support. Vlibe aperture ot the plate 22d in which the link or rod 20d engages may be readily deteu mined, audit will be noted that in this coustruction, as well as the others, the tension nieinber or connection between the door and body support is above the anis ot the door hinge when the body is'in dumping position with the door swung open, andthe tension connection or member will pull the door lo closed position when the body is returned to normal position. l

Fig. 8 illustrates in diagram the use ot the improven'ients on a twoway dump body, lil'3 indicating the bottoni of the body to the opposite efg'es ot' which are hinged, as at 19e, the opposite side doors 18e. The bottom le@ is hinged at the longitudinal center line, as at 15e, on the 'traine 17e ot the truck or car, so that the body may be tilted toward either side to dumping position. Each door 1Se has the inwardly extending arni 23e to which the link or connection 2()e is connected, as at 25C, and the lower ends of the links or elements Y2Oe are connected, as at 22e, with the traine 17e in the manner hereinbetore described. lVhen the'body is dumped toward 'either side the link or element 20G at the opposite side is disconnected from the traine 17e so astopermit the corresponding side door 155e to move upwardly with the body while the side door which is moved downwardly will swing open. For example, Fig. 8 shows, in dotted lines, the body tilted toward the right, with the right side door swung open, and the lett sidedoor raised wit-litho body and its link or connection- 20e disc-onnected from the trame 17@ and hanging loosely. In the same way, the body .may be dumped toward the lett, with the lett hand link or element 2Oe connected to the trame 17e and the right hand link 20 disconnected from said frame.
